These statements support established R&D capability, though they do not document specific patents, new product launches, or measurable innovation outcomes.

Production capacityThe supplier describes machining equipment including large-scale lathes, boring, drilling, milling, and welding machines, and reports annual productivity of 2,000 sheet-metal machine sets. It also states a peak-season fulfillment time of 2–3 months and production of multiple machine categories, supporting a documented production base.

Customization capabilityThe supplier states that it introduces suitable products according to customer requests and provides solutions across multiple machine types, including three- and four-roll bending machines, angle rolls, laser cutting machines, and press brakes. Its description of CNC equipment handling complex, fine, small-batch, and varied parts further supports flexibility, although no specific customized project is documented.

Product Q&A

Q:What is the service life of your product?

The longevity of our Automatic 4 Roll Hydraulic Plate Roller highly depends on the operator's skills, experience, and daily working hours. With proper maintenance and adherence to operational guidelines, the machine can last up to an impressive 10 years. Note that extended daily use, such as operating for 12 hours or more, may impact its overall service life.

Q:What are the specific categories of your products?

We proudly offer three main categories of roll bending machines: Mechanical 3 Roller, Hydraulic 3 Roller with Pre-Bending, and Hydraulic 4 Roller with Pre-Bending. Each type is designed to meet various industrial needs.

Q:What are the specifications and styles of your existing products?

Our product range includes both light and heavy-duty rolling machines, accommodating thicknesses from 6mm to 150mm and widths from 1000mm to 12000mm. Additionally, we can customize machines to meet specific customer requirements, such as smaller rolling diameters or specialized applications like oil pipes, wind towers, and loaders.

Q:What industries can this machine be used in?

This machine is ideal for shipyards, wind tower construction, boilers, pressure vessels, heat exchangers, and general steel structure fabrication.

Q:Does the machine require pre-bending both ends?

No, unlike 3-roll designs, this machine eliminates the need for pre-bending both ends before rolling the entire cylinder, completing the process in a single pass.
